Blueberry plant named &#34;bb07-210fl-18&#34;

ABSTRACT

A new and distinct cultivar of blueberry plant named BB07-210FL-18 as described and shown herein. BB07-210FL-18 is a new and distinct low chill tetraploid Southern highbush blueberry ( Vaccinium ) variety of complex ancestry, based largely on  V. corymbosum, V. ashei,  and  V. darrowii,  with a limited contribution from  V. tenellum  and  V. fuscatum.  It is a productive early season ripening variety with high quality fresh market characteristics and is intended for areas which successfully grow lower chill Southern highbush varieties. The flavor is very good with a balance of medium amounts of sweetness and acidity. Berries have a crunchy and juicy texture with medium storage ability of 2 to 3 weeks.

BACKGROUND AND SUMMARY

Blueberries are a well-known fruit enjoyed by many throughout the world.One example of an existing, patented blueberry variety is Star, U.S.Plant Pat. No. 10,675. Another example of an existing, patentedblueberry variety is Emerald, U.S. Plant Pat. No. 12,165.

Compared to Star, the maturity of the present cultivar, BB07-210FL-18,is earlier by 5-7 days; new canes are green color compared to yellowishfor Star; and, BB07-210FL-18 has a larger berry with rounder shape, moreconsistent sizing throughout the harvest season, and a slightly sweetertasting berry.

Compared to Emerald, the maturity of BB07-210FL-18 is earlier by 10days; the bush shape is more upright with a less brushy habit; and theberry has a lighter blue colored, more rounded shape. Also, the harvestseason is more concentrated than Emerald.

The present cultivar, BB07-210FL-18, provides one or more advantagescompared to these and/or other blueberry varieties such as one or moreof an early maturity and more easily harvested blueberry.

DETAILED DESCRIPTION

Note: statements of characteristics herein represent exemplaryobservations of the cultivar herein and will vary depending on time ofyear, location, annual weather, etc. Where dimensions, sizes, colors,and other characteristics are given, it is to be understood that suchcharacteristics are approximations and averages. The descriptionsreported herein are largely from specimen plants grown near Interlachen,Fla. Data were obtained on plants that were 5 years old.

Cultivar Name: BB07-210FL-18.

Classification:

Family: Ericaceae

Botanical name: Vaccinium corymbosum

Common name: Blueberry

Parentage:

FEMALE PARENT

Name: Springhigh (FL 91-226 unpatented×Southmoon U.S. Plant Pat. No.9,834).

U.S. Plant Pat. No. 16,404.

Compared to Springhigh, BB07-210FL-18 has a wider leaf width, lighterleaf color, wider corolla opening, and a lighter color of style.BB07-210FL-18 averages fewer flowers per cluster, wider and less tallberry shape, different color of ripe berry with and without bloom, morepronounced calyx shape and size. The mean date of first harvest is 10days later.

MALE PARENT

Name: Springwide (FL83-132 unpatented×Sharpblue unpatented).

U.S. Plant Pat. No. 16,333.

Compared to Springwide, BB07-210FL-18 has a more upright bush shape withfewer mature canes, slightly longer, wider leaf, blooms 10 days earlier,berry harvest more concentrated and mean 50% ripe date is 10 days later,slightly smaller berry, more loose berry cluster.

BB07-210FL-18 was first asexually propagated by softwood cuttings. Forexample, softwood cuttings were first taken and rooted in the spring of2009 in Grand Junction, Mich., and have been propagated several timessince in succeeding years. All propagated plants have retained theoriginal characteristics. Softwood cuttings root readily as domicroshoots from tissue culture.

All field observations were made in Spring 2012 on a 5-year oldindividual plant located in a seedling plot near Interlachen, Fla.Laboratory analysis of fruit characteristics were done in GrandJunction, Mich.

General comments: BB07-210FL-18 is a new and distinct low chilltetraploid Southern highbush blueberry (Vaccinium) variety of complexancestry, based largely on V. corymbosum, V. ashei, and V. darrowii,with a limited contribution from V. tenellum and V. fuscatum. It is aproductive early season ripening variety with high quality fresh marketcharacteristics. It is intended for areas which successfully grow lowerchill Southern highbush varieties. Winter chilling requirements forsuccessful flowering and leafing are approximately 200-300 hours (<7°C.). Plants of BB07-210FL-18 are medium upright with modest growth ofprimary canes and laterals. Flowering and leafing are synchronous.Flowering is early (northern Florida) and may require frost protectionfor successful pollination. Plant vigor is very good and does not appearto be overly susceptible to foliar and soil diseases if normalhorticultural practices are followed. Its berries are well exposed, verylarge with a small and dry picking scar, excellent medium blue colorwith a medium amount of bloom, which is modestly maintained duringhandling. The flavor is very good with a balance of medium amounts ofsweetness and acidity. Berries have a crunchy and juicy texture withmedium storage ability of 2 to 3 weeks. Thus, BB07-210FL-18 provides anearly maturing variety with a concentrated harvest, and very large berrysize with excellent eating qualities.
